### Creating a Quick Scan on a Single Polyline

You can use the Quick Scan functionality to create a quick scan on a single polyline. The polyline can be open-ended or closed. For more information about quick scans, see "Creating Quick Scans".

To create a quick scan on a single polyline, do the following:

1. In your Edit window, click to define where to insert the new feature.

2. Select Curve mode (Operation | Graphic Display Window | Change Curve/Surface Mode).

3. In the Graphic Display window, hover the pointer over the CAD element polyline.

4. Press Ctrl + Shift and click on the polyline from which you want to start the scan. Drag the pointer along the polyline and in the direction of the scan.

5. Release the mouse button. PC-DMIS creates a scan and inserts it at the cursor position as follows:

- If the polyline is open-ended, PC-DMIS generates the path from the point where you clicked to create a gesture up to the end of the polyline, minus the distance equal to the value that is entered for the Offset option on the Path Definition tab in the Linear Open Scan dialog box.
  For a laser probe, the scan is created until the end of the polyline.

- If the polyline is closed, the scan is all-around. It starts from the point where you clicked to create a gesture.
